4 Claims.

My invention relates to devices for disposing of snow, and particularlyto mechanically operated devices for removing or melting snow.

One object of my invention is to provide a snow remover which isattachable to the ordinary motor truck, and which shall operate toplough through the snow as the truck advances, collecting the snow andeither melting it and discharging the water from the device, or at will,discharging the snow collected at one side of the path of progress.

A second object is to provide a device of the character described, whichis simple in construction, economical in operation, and one that can beattached to or removed from the front end of a truck or other vehiclewith facility and without material change in the vehicle.

My invention consists in the novel construction and operation and thecombination of elements to attain the specified objects. In theaccompanying specifications and claims, and the drawing forming a partthereof, I have described and illustrated a preferred embodiment of myinvention as adapted for use with a motor truck of the usual type, butmodifications may be made within the scope of the claims, both in designand construction which would adapt the invention for use with other orsmaller types of propelled vehicles.

In the drawing,

Fig. 1 is a front elevation of one embodiment of my invention, partiallyin section on the line I I, Fig. l2.

Fig. 2 is a plan showing the device as attached to the front of a motorvehicle, partially in section on the line 2 2, Fig. 1.

Fig. 3 is a sectional end elevation, substantially on the line 3 3, Fig.1.

Referring to the drawing,

I0 is a chamber, secured to the front end II of a motor truck bysuitable braces I2, I3, I4. This chamber is an elongated chamber, and isattached to the truck lateral to the path of movement thereof. The frontwall, I5, of this chamber, is open at the base, the opening extendingbetween end walls, to permit the snow to enter as the truck advances inthe direction of the arrow I6.

Mounted in this chamber and movable in the direction of its length, arethe endless chains I'I, connecting which are a plurality of blades I8,forming movable partitions as the chains are moved by suitable means,here shown by the sprockets |9--20 rigid With the shaft 2I, connectingwith motive power on the truck, and invment respectively to thesprockets 25, 26, rigid with the shafts 21, 28 on which are also rigidlymounted the sprockets 29, 30, actuating the chains I7. Rollers 3ljournalled on the cross rods 32 support the upper conveyor line ofchain, .and similar rollers 33 prevent the lower chain line from risingwhen in operation to move the collected snow. As the truck advances,with the snow remover in operation, the snow as it collects in thechamber, is moved by the conveyor blades in the direction of the arrow34, and carried over within the chamber at 35, discharging between thechains I'I into the receptacle 36, pan like in form, and mounted betweenthe chains, extending between the front and rear walls of the chamber towhich it is secured.

Mounted beneath the receptacle are a plurality of burners 31,here shownas burning liquid fuel, and exten-ding through the rear wall 38, of thechamber and connecting with the fuel main 39, supplied from the tank 40mounted in a convenient location, here shown .as on the top of thechamber. As the snow is melted the water discharges from the receptacle,through the pipe 4I.

In some cases, particularly on wide main thoroughfares, it may bepreferable to discharge snow from the chamber, rather than to melt it,and in that event I have provided a gate 42, at the end of the chambertoward which the snow is moved.

With this gate opened as at 42', the snow is discharged from the chamberat the right side of the road, clearing the path as the truck advances,but piling the snow instead of melting it, as is the case when the gateis closed and the snow carried over to discharge into the meltingreceptacle.

Having thus described my invention, I claim:- 40

1. A snow remover comprising in combination, an elongated chamberadapted to be secured laterally to the front of a propelled vehicle, andto be supported thereby adjacent to the road surface, and having itsfront wall open at the base between the end Walls; an endless conveyormounted within the chamber and movable in the direction of its length,comprising a pair of chains and a plurality of connecting blades,extending normal to the axes of the chain lines, 50 and forming movablepartitions; means for moving the conveyor continuously; and an openingin one end wall, through which snow admitted through the opening in thefront wall may be discharged from the chamber; and a closure 55 movablysecured to the chamber and operative to close the opening in the endwall; a receptacle mounted within the chains of the conveyor and securedto the front and rear walls of the walls of the chamber, and having aconduit discharging outside the chamber; and means for melting snowdeposited in the receptacle by the conveyor.

2. In a snow remover of the character described in claim 1, means forheating the receptacle comprising a plurality of burners operativebeneath the receptacle.

3. In a snow remover of the character described in claim 1, a pluralityof burners operative to heat the receptacle; a source of supply forliquid fuel; and connections therefrom to the burners.

4. A snow remover comprising in combination, an elongated chamberadapted to be secured laterally to the front of a propelled vehicle, andto be supported thereby adjacent to the road surface, and having arcuateend walls, and having its front wall open at the base between the endwalls; an endless conveyor mounted within the chamber and movable in thedirection of its length, comprising a pair of chains and a plurality ofconnecting blades, extending normal to the axes of the chain lines, andforming movable partitions; means connecting with a source of motivepower, whereby the conveyor may be moved continuously; a receptaclemounted within the chains of the conveyor and secured to the front andrear Walls of the chamber, and adapted to receive snow from the conveyoras it moves thereacross, and having a conduit therefrom dischargingoutside the chamber; and means for heating the receptacle continuouslywhen the snow remover is in operation to melt snow deposited therein bythe conveyor.
